MLV Manufacturer and Product-Family Research Map

This page maps manufacturer and product-family evidence found during UBAEC’s MLV research through 2026-08-11. It helps readers find official product pages, datasheets and lifecycle clues. It does not rank suppliers, measure market share, approve vendors or claim that the list is exhaustive.

How to Read the Map

Current official evidence: an official manufacturer page or document supported an active/current family at the review date.
Current with conditions: useful official evidence exists, but construction, revision, qualification, regional availability or exact family scope needs confirmation.
Historical or audited absence: historical product evidence exists, or the current site was checked without finding an equivalent current family. Absence is not a formal blanket EOL notice.

Every exact selection still requires the current order-code datasheet, revision, lifecycle, test conditions and supplier confirmation.

Current Official Manufacturer Evidence

Manufacturer	Research themes found	Required caution
TDK / TDK Electronics	Chip varistors/CTVS, ESD, automotive and application/technology material	Confirm exact series, test setup and qualification scope
Panasonic Industry	EZJ chip-varistor families, selection, mounting and reliability guidance	Keep chip MLV and ZNR/disc-varistor roles separate
Bourns	MLA/MLC/MLD/MLU/CGA and ChipGuard portfolio evidence	Portfolio name can span technologies; exact family controls construction
KYOCERA AVX	TransGuard, arrays, filters/feedthrough and automotive/specialized families	Separate topology and per-line/package ratings
Eaton	MLVB/MLVC/AMLV families and higher-energy application material	Keep MOVS molded surface-mount MOV outside the ceramic-MLV matrix
Vishay	Multilayer varistor product documents and exact-model parameter evidence	Verify current order code, suffix and waveform
Fenghua Advanced Technology	Chinese/English multilayer chip-varistor families including high-voltage themes	Retain exact safety, pulse and model conditions
Sunlord	Chip-varistor families including high-voltage and automotive themes	High-voltage family evidence does not generalize to all MLVs
Littelfuse	MLA/AUML and specialized MLV application families	Resolve page/PDF revision and family-table conflicts before numeric use
Thinking Electronic	TVM-series chip-varistor and automotive evidence	Confirm exact range, model and qualification wording
INPAQ	MLVS families, automotive/high-voltage and array/topology evidence	Resolve document revision and added-size scope
YAGEO Group / KEMET document route	KEMET-branded VC/VE/VA/VG multilayer-family and legacy documents; the former KEMET varistor route now redirects to YAGEO Group	Keep plastic-encapsulated VP SMD MOV separate and verify the current branded family, lifecycle and order code
KOA	NV73 and related chip-varistor evidence	Confirm order-code lifecycle, replacement and part-level qualification
MARUWA	CVA/CVT/CVX family and automotive/high-surge research evidence	Reject mislinked or mismatched-language documents for model data
Walsin	VZ/VH family and multilingual product evidence	Confirm current branded part lists and exact ESD/test scope
AMOTECH	Current manufacturer MLV and application documentation	Exact family construction and order code remain controlling
NIC Components	MLV-related portfolio evidence plus adjacent ESD products	NXED construction is resin/thick-film and stays outside ceramic MLV aggregation
AEM Components	ES, NA, HA, HV and HSP families; low-capacitance, surge and network variants	Keep ordinary MLV, HSP network and MVF filter-array structures separate
SFI Electronics Technology	Official ZnO MLV pages, automotive/load-dump development and patent trail	Keep MLV, CSPD and semiconductor/SGD structures separate
Semiware	SME low-capacitance and SMV surge/high-voltage catalog evidence	SMV1812 construction remains a hold pending cross-section/material evidence
Meritek	MVS-T, MVS-H, MVS-A and MVS-L family evidence	Keep multilayer families separate from encapsulated SMD MOV/TMOV products

Historical or Lifecycle-Boundary Evidence

TAIYO YUDEN and Murata have historical MLV-related evidence in the research corpus. The current-site audit did not establish an equivalent current family at the review date. This is an audited absence, not a claim that every former order code is formally discontinued. A blanket EOL statement requires an official model/family PCN or lifecycle notice.

Companies Not Promoted as Current MLV Manufacturers

Some targeted searches returned disc MOV, molded MOV, TMOV, distributor-only, archival or ambiguous evidence rather than a verified current ordinary MLV family. These search decisions do not claim that a company has never made an MLV. New primary evidence can reopen the classification.

How to Verify a Manufacturer Family

Use the manufacturer’s canonical product domain.
Confirm construction, family and exact order code.
Check document revision and access date.
Keep translations and regional pages attached to one technical canonical.
Verify VDC/VAC, Vvar/current, Vc/current/waveform, Imax/energy, capacitance, leakage and temperature under original conditions.
Confirm qualification and lifecycle for the exact part.
Validate the actual application and PCB.

Use the MLV Technical Resources & Datasheet Library for curated source links, MLV datasheet parameters and test conditions for comparison rules and How to Select an MLV for the engineering workflow.

Summary

This map records what the evidence showed on a stated date. It is designed for source discovery and lifecycle-aware research, not supplier ranking or substitution. Recheck the exact current product before every public claim or design decision.
